    In the previous video, Ben laid down the foundation for a VGA controller - generating the sync signals - by practicing his acupuncture skills on a few breadboards, using a 10 MHz crystal oscillator to drive a handful of 4-bit counters, NOTs and NANDs. In this video he adds an EEPROM and some more circuitry to push out 100x75 64-colors pixels to a physical screen.

    The schematics and part list are on his website, which won't work on one of his breadboard computers - it requires JS to be enabled.

    I always love technical videos like this. They're extremely hard to make interesting but Ben Eater is very good at keeping things engaging, even though most of this video is just him doing math...

    I always love technical videos like this. They're extremely hard to make interesting but Ben Eater is very good at keeping things engaging, even though most of this video is just him doing math and wiring a breadboard.
